Noxious stimuli in our environment are often accompanied by input from other sensory modalities that can affect the processing of these stimuli and the perception of pain. Stimuli from these other modalities may distract us from pain and reduce its perceived strength. Alternatively, they can enhance the saliency of the painful input, leading to an increased pain experience. We discuss factors that influence the crossmodal shaping of pain and highlight the important role of innocuous stimuli in peripersonal space. We propose that frequency-specific modulations in local oscillatory power and in long-range functional connectivity may serve as neural mechanisms underlying the crossmodal shaping of pain. Finally, we provide an outlook on future directions and clinical implications of this promising research field.
我们所处环境中的有害刺激通常伴随着来自其他感觉模式的输入,这些输入会影响对这些刺激的处理和疼痛感知。来自这些其他感觉模式的刺激可能会分散我们对疼痛的注意力并降低其感知强度。或者,它们可以增强疼痛输入的显著性,从而导致疼痛体验增加。我们讨论了影响疼痛的跨感觉塑造的因素,并强调了无害刺激在近体空间中的重要作用。我们提出,局部振荡功率和长程功能连接的频率特异性调制可能是疼痛跨感觉塑造的神经机制。最后,我们对这个有前途的研究领域的未来方向和临床意义进行了展望。
